Caution
Please read the following before
installing the unit
Due to its heavy weight, the unit should be installed
with great care.
Installation of the unit requires two persons.
Use tools carefully while installing of the unit.
Be sure that the cabinet that is used is sturdy enough
to support the weight of the unit.
To reduce the risk of fire, do not place any heating or
cooking appliance beneath this unit.
Install the unit so that its AC power cord can be
connected directly to a wall outlet. Do not use a
converter or extension cord.
Be sure that the AC power cord has no slack during
use of the unit, since the cord acts as an FM wire
antenna. If the AC power cord has some slack, wind
it around the cord hook so as to eliminate the slack.
The unit has a built-in ferrite bar antenna for AM
radio reception. Confirm that AM reception is
acceptable before finally attaching the unit.
Install the unit as far as possible from sources of
noise (for example, a refrigerator, microwave oven or
fluorescent lamp).
This unit is not waterproof. Install it where it will
not be exposed to splashing by water, as this may
damage the unit.
To reduce the risk of fire or electric shock, do not
touch the AC power cord with wet hands.
Never place objects between the top of the unit and
the bottom of the cabinet. This could cause the unit
to fall.
Make sure the unit’s four screws are fastened tightly.
After installing the unit, do not pull down on it or
hang something heavy on it.
1 Decide on the installation location and
orientation of the unit based on the best
reception that is possible (see “Improving
the reception”).
2 Mark the position of the 4 holes by using
the supplied template. Use a drill to make
the holes (size 6.5 mm diam., 9/32 inch). (See
Fig. -)
3 When the cabinet door overhangs the shelf
and obstructs the unit, you can adjust the
unit/shelf height.
First set the L mark to the dot which
becomes the lowest position, then you
can adjust the height in 4 steps (HL)
by turning the spacer counterclockwise
(See Fig. -). The unit can be installed
without the spacer.
4 Install the unit with the supplied mounting
screws. (See Fig. -)
Note
If you lose the supplied screws, please purchase #10 or
M5 screws.
About the backup battery
To keep good time, this unit contains one CR2032
battery inside of the unit as a backup power source.
The battery keeps the clock operating in the event of a
power interruption.
Knowing when to replace the
battery
When the battery becomes weak, “” appears in the
display.
If a power interruption occurs while the battery is
weak, the current time will be initialized.
Replace the battery with a Sony CR2032 lithium
battery. Use of another battery may cause a fire or
explosion.
Note
If “AM 12:00” flashes in the display when the unit is
connected to AC outlet for the first time, the battery
may be weak. In this case, consult your Sony dealer.
Replacing the battery
1 Keep the AC plug connected to the AC
outlet and pry out the battery holder at the
bottom of the unit using a slender rod, such
as a screwdriver. (See Fig. -)
2 Push the exhausted battery out from the
bottom of the battery holder and insert a
new battery with the side facing up. (See
Fig. -)
3 Insert the battery holder back into the unit.
(See Fig. -)
4 Press RADIO/BAND, CD , or AUDIO IN
to turn “” off in the display.
Note
When replacing the battery, do not disconnect AC
plug from AC outlet.
If you do, the current time will be initialized.
Battery Warning
If the unit is to be left unplugged for a long time,
remove the battery to avoid undue battery discharge
and damage to the unit from battery leakage.
NOTES ON THE LITHIUM BATTERY
Dispose of the used battery promptly. Keep the
lithium battery out of the reach of children.
Should the battery be swallowed, consult a doctor
immediately.
Wipe the battery with a dry cloth to assure a good
contact.
Be sure to observe correct polarity when installing
the battery.
Do not hold the battery with metallic tweezers,
otherwise a short-circuit may occur.
Do not expose the battery to excessive heat such as
direct sunlight, fire or the like.
WARNING
There is a danger of explosion if the battery is
incorrectly replaced.
Replace only with the same or equivalent type
recommended by the equipment manufacturer.
Installing the batteries into
the remote commander
(See Fig. -)
Insert two size AAA (R03) batteries (not supplied).
When to replace the batteries
With normal use, the batteries should last for about
six months. When the remote no longer operates the
CD kitchen clock radio, replace all the batteries with
new ones.
Notes
Do not charge the dry batteries.
If you do not intend to use the remote for a long
time, remove the batteries to prevent damage by
leakage and corrosion.
Use of magnet (See Fig. -)
A magnet is provided on the back of the remote so
that it can be attached a refrigerator or other iron
surface.
However, do not operate the remote while it is
attached in this manner.
Note
Do not place the remote commander near magnetic
cards such as credit cards.
